Highlights of UBIKLoadPack GWT

With all the good features below I would like to add a very important note – without this plugin it is near impossible to test GWT applications. The plugin reduces the complexity by many orders of magnitudes.

Extract, Variables, Assertions	Modify request via variables to alter request Parse response and store XML in variable Extract via XPath
The magic	GWT Pre Processor manages requests GWT Post Processor used to convert on response Recording template provided with plugin
Helpers	GWT Serialization jar Find missing classes
